Laju Pertumbuhan Lamun Enhalus acoroides yang Di Transplantasi dengan Menggunakan Metode Terfs Di Perairan Pantai Desa Waai Kabupaten Maluku Tengah

Coastal utilization that is not directed by the surrounding community such as sand and stone extraction and disposal of solid and liquid waste to the beach can cause damage to coastal ecosystems including seagrass ecosystems. Efforts to restore the diminishing condition of the seagrass ecosystem is through seagrass transplantation activities using the TERFS (Transplanting Eelgrass Remotely With Frame System) method. This research was conducted from February 2019 - 31 May 2019. This study aimed to analyze the survival rate and growth rate and physical chemical factors of the waters that affect the growth of the seagrass Enhalus acorides transplanted using the poly bag method and the TERFS method (Transplanting Eelgrass Remotely With Frame System) in the coastal waters of Waai Village, Central Maluku Regency. The results showed that the Enhalus acorides seagrass had a survival rate of 100%. The value of the growth of seagrass for three weeks of observation is in frame 1 of 0.43 cm / day, in frame II of 0.47 cm / day and in frame III of 0.46 cm / day. The average value of the physical chemistry parameters of the waters at the transplantation location using the coastal waters of Waai Village, Central Maluku Regency is still within the range of environmental parameters of the marine waters supporting the growth of seagrass Enhalus acorides, including temperatures of 30.67 ℃, brightness of 100%, water depth of 45.67 cm, current velocity of 0.46 cm / sec, salinity of 29 ‰ and water pH of 7.53. The average value of nitrate content in the water colum

Analisis Kandungan Merkuri (Hg) dan Kadar Klorofil Lamun Enhalus Acoroides Di Perairan Marlosso dan Nametek Kabupaten Buru Provinsi Maluku

Seagrass is a type of vegetation that is able to live and develop well in coastal areas and is a habitat for several types of marine animals,such as sea cucumbers, sea urchins, starfish and sea urchins. Seagrass is an organism that is susceptible to pollution of the coastal environment such as mercury (Hg) so that it has an impact on the chlorophyll content of seagrass leaves. This study aims to determine the content of heavy metal Hg and its relationship with the chlorophyll content of seagrass Enhalus acoroides in the waters of Marlosso and Nametek in Buru District Maluku Province. The study was conducted in May 2018 and laboratory analysis was conducted in June 2018. Samples were taken at two stations namely Nametek Beach and Muos Sungai Marlosso. The results showed that the content of heavy metal Hg in roots> rhizoma> seagrass leaves. The content of heavy metals and seagrass chlorophyll content has a negative correlation where the Hg metal has a correlation of (r = - 0.97) and indicates that the higher the content of heavy metals will reduce the seagrass chlorophyll conten

Kerapatan Dan Penutupan Lamun Di Perairan Desa Tayando Yamtel Kecamatan Tayando Tam Kota Tual.

Research on the density and cover of seagrass in the waters of Tayando Yamtel Village, Tam District, Tual City, was carried out in March-May 2018, using the quadrant linear transect method. The results of the study found three species of seagrass, namely Cymodocea rotundata, Cymodocea serrulata and Thalassia hemprichii. The highest density values at stations I and III were Cymodocea rotundata, namely 90.598 ind/m2 and 80.02 ind/m2. The highest density value at station II was Cymodocea serrulata, which was 88.24 ind/m2. The total density of all species at each station is included in the dense category with the status of seagrass conditions in the waters of Tayando Yamtel Village at station II being in good, healthy and rich condition, while at stations I and III in less healthy and less rich conditions

Keanekaragaman Gastropoda Pada Habitat Lamun Di Perairan Desa Tayando Yamtel Kecamatan Tayando Tam Kota Tual

The gastropod community is an important component in the food chain in seagrass beds, where the gastropods are the detritus feeder. Research on the diversity of gastropods in seagrass habitat in the waters of Tayando Yamtel Village, Tam City, Tual District, was conducted in March-May 2018, using the quadrant linear transect method. The results of measurements of environmental parameters in Tayando Yamtel waters are: an average pH of 8.55; DO 6.59 µg / l; salinity 32.36 ‰; temperature of 29 ° C; TDS 24.7 mg / l; current velocity (0.42 m / sec) is classified as low current; and a depth of 1.5 m. Gastropod research results obtained 862 individuals consisting of 15 families and 30 species of gastropods, while for seagrass obtained 3 species namely Cymodocea rotundata, Cymodocea serrulata and Thalassia hemprichii. The highest value of composition and gastropod density at Station I was dominated by Psedeovertagus aluco species at 62.73% and 3.708 (ind / m2), while at Station II were 28.01% and 0.93 (ind / m2) and Station III were 38.46% and 0.15 (ind / m2) are dominated by Strombus gibberulus species. Based on the gastropod ecological index value, the index value of species diversity and harmony is included in the medium category and the index value of dominance is in the low category.
